Actually I see what MW's after now - what I refer to as a 'phrase sampler' (I love's my Roland SP-808!) And it's actually not a bad idea for Rich to consider.
But that definately is what get's the Aphex Twin nuttiness. To repeat, reverse, insert any piece of audio obtainable and arrange triggerable durations on a finite grid - that is pretty freakin' nice!
The only problem is MW, it's going to be contested that this can already be done in Audio Track, with DR, or set your ninja chops in OP's sampler. I'm definately interested in the MOTU product you've shown, and some form of it in Orion in future - I'd be for it. Those who haven't worked like George Martin, on a Akai MPC, or a Roland SP-808, they're just not going to get it from here on in.
Phrase sampling in OP - indeed!
